This is a constant bug for me on 900a. Fn+F2 will switch wireless
off, but not back on. Running the wireless scripts manually results
in:
off:
tre...@myri:/etc/acpi/actions$ sudo sh wireless.sh off
Detected eeepc-wlan as rfkill /sys/class/rfkill/rfkill0
Detected WLAN module ath5k on wlan0
On:
tre...@myri:/etc/acpi/actions$ sudo sh wireless.sh on
Detected eeepc-wlan as rfkill /sys/class/rfkill/rfkill0
Detected WLAN module ath5k on wlan0
wlan0: ERROR while getting interface flags: No such device
exec: 51: wireless.sh: not found
these last two lines are strange. Please run the command with shell
echo (-x):
$ sudo sh -x /etc/acpi/actions/wireless.sh on
and post the output.

After running this time, I got a new behavior in which thee led also
shut itself off - makes sense given that the script is calling itself to
do just that. The last bit of dmesg gives
tre...@myri:~$ dmesg | tail

hmm...noticing the "ifconfig up" stanza...I'm going to try commenting it
out to see what that does.
commenting this line
# if ! ifconfig $WLAN_IF up; then exec $0 off; fi
results in duplication of the old behavior (hardware indications are
that wifi should work, software doesn't read anything). Interestingly, a
call to lspci seemss to indicate that I have a "Atheros Communications
Inc. AR5001 Wireless Network Adapter". Isn't the hardware actually an
AR242X or some such thing?
Also, I am not sure how the script interacts with 2.6.30 kernel you
are using; the kernel shall turn on rfkill on Fn+F2 before the script
kicks in.
I had the same issue with 2.6.29 when it was the backport too, I just
never used the toggle enough to care and didn't have enough time to go
poking around for fun.
